// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
* Settings class to configure an instance of {@link QueryServiceStub}.
*
* The default instance has everything set to sensible defaults:
*
*
* - The default service address (monitoring.googleapis.com) and default port (443) are used.
*
- Credentials are acquired automatically through Application Default Credentials.
*
- Retries are configured for idempotent methods but not for non-idempotent methods.
*
*
* The builder of this class is recursive, so contained classes are themselves builders. When
* build() is called, the tree of builders is called to create the complete settings object.
*
*
For example, to set the
* [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
* of queryTimeSeries:
*
*
{@code
* // This snippet has been automatically generated and should be regarded as a code template only.
* // It will require modifications to work:
* // - It may require correct/in-range values for request initialization.
* // - It may require specifying regional endpoints when creating the service client as shown in
* // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
* QueryServiceStubSettings.Builder queryServiceSettingsBuilder =
* QueryServiceStubSettings.newBuilder();
* queryServiceSettingsBuilder
* .queryTimeSeriesSettings()
* .setRetrySettings(
* queryServiceSettingsBuilder
* .queryTimeSeriesSettings()
* .getRetrySettings()
* .toBuilder()
* .setInitialRetryDelayDuration(Duration.ofSeconds(1))
* .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))

* .setMaxRetryDelayDuration(Duration.ofSeconds(30))

* .setRpcTimeoutMultiplier(1.5)

* .build());
* QueryServiceStubSettings queryServiceSettings = queryServiceSettingsBuilder.build();
* }
*
* Please refer to the [Client Side Retry
* Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
